CentOS 6.4安装Nagios 3.5.0监控利器的教程

发布时间:2020-05-16编辑:脚本学堂
本文介绍下,在centos6.4系统中安装最新的监控利器nagios 3.5.0的详细过程,有需要的朋友,可以参考学习下。

本节分享在centos6.4系统中,安装与配置nagios3.5.0的方法。

一,安装环境的配置
1,关闭防火墙
 

复制代码 代码示例:
[root@Nagios ~]# service iptables stop
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@Nagios ~]# chkconfig iptables off

2,关闭SElinux
如果未关闭selinux,则可能在安装完成后,会出现Internal Server Error错误
编辑/etc/selinux/config
 

复制代码 代码示例:
[root@Nagios ~]# vim /etc/selinux/config
将SELINUX=disabled
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

3,修改hosts文件
 

复制代码 代码示例:
已知我们这台机器的主机名为Nagios,则修改/etc/hosts
127.0.0.1  Nagios localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
 

添加上面红色部分即可,否则启动apache服务的时候可能出现
Starting httpd: httpd: apr_sockaddr_info_get() failed for Nagios

做完以上3个步骤后,需要重启服务器

二,软件的准备
1,安装必要的软件
 

复制代码 代码示例:
[root@Nagios ~]# yum -y install wget make openssl openssl-devel httpd php gcc glibc
> glibc-common gd gd-devel net-snmp mysql
> mysql-server mysql-devel php-mysql perl perl-devel gnutls gnutls-devel

2,MySQL的配置(此步可省略)
虽然现在还并未使用MySQL,但是在以后的配置需要用到。
首先启动MySQL服务器
 

复制代码 代码示例:
[root@Nagios ~]# service mysqld start
 

接着设置更改MySQL root账户的密码
 

复制代码 代码示例:
[root@Nagios ~]# mysqladmin -u root password 123456

三,软件的安装
1,Nagios账户及组的添加
 

复制代码 代码示例:
[root@Nagios ~]# useradd nagios
[root@Nagios ~]# groupadd nagcmd
[root@Nagios ~]# usermod -a -G nagcmd nagios
[root@Nagios ~]# usermod -a -G nagcmd apache

2,软件的下载
 

复制代码 代码示例:
Nagios软件的下载
[root@Nagios ~]# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.5.0.tar.gz
[root@Nagios ~]# wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz

3,Nagios软件的解压
 

复制代码 代码示例:
[root@Nagios ~]# tar zxvf nagios-3.5.0.tar.gz
[root@Nagios ~]# tar zxvf nagios-plugins-1.4.16.tar.gz

4,Nagios的编译与安装
1)、首先进入Nagios解压后所在的目录
 

复制代码 代码示例:

[root@Nagios ~]# cd nagios
[root@Nagios nagios]# ./configure --with-command-group=nagcmd
[root@Nagios nagios]# make all
[root@Nagios nagios]# make install
[root@Nagios nagios]# make  install-init
[root@Nagios nagios]# make  install-config
[root@Nagios nagios]# make  install-commandmode
[root@Nagios nagios]# make  install-webconf

[root@Nagios nagios]# cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/
[root@Nagios nagios]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers/
 

2)、测试nagios的配置文件
 

复制代码 代码示例:
[root@Nagios nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
 

如果最后出现
Total Warnings: 0
Total Errors:   0

Things look okay - No serious problems were detected during the pre-flight check
就证明nagios配置无误可正常启动!

3)、启动Nagios服务:
 

复制代码 代码示例:
[root@Nagios nagios]# service nagios start
Starting nagios: done.


启动httpd服务:
 

复制代码 代码示例:
[root@Nagios nagios]# service httpd start
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName    [  OK  ]
 

4)、添加访问WEB服务的账户及密码
 

复制代码 代码示例:
[root@Nagios nagios]# htpasswd -c /usr/local/nagios/etc/htpasswd.users admin
New password:
Re-type new password:
Adding password for user admin
 

此时已添加好了访问web网站的用户。

5,Nagios plugin的安装
首先,进入Nagios plugin解压目录
 

复制代码 代码示例:
[root@Nagios nagios]# cd ../nagios-plugins-1.4.16


进行编译:
 

复制代码 代码示例:
[root@Nagios nagios-plugins-1.4.16]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-extra-opts --enable-perl-modules --enable-libtap
编译成功后,会出现如下信息:
          --with-apt-get-command:
             --with-ping6-command: /bin/ping6 -n -U -w %d -c %d %s
              --with-ping-command: /bin/ping -n -U -w %d -c %d %s
                      --with-ipv6: yes
                     --with-mysql: /usr/bin/mysql_config
                   --with-openssl: yes
                    --with-gnutls: no
              --enable-extra-opts: yes
                      --with-perl: /usr/bin/perl
            --enable-perl-modules: yes
                    --with-cgiurl: /nagios/cgi-bin
              --with-trusted-path: /bin:/sbin:/usr/bin:/usr/sbin
                  --enable-libtap: yes

#-----插件的安装
 

复制代码 代码示例:
[root@Nagios nagios-plugins-1.4.16]# make
[root@Nagios nagios-plugins-1.4.16]# make install

将nagios及httpd加入启动项,并自动启动:
 

复制代码 代码示例:
[root@Nagios nagios-plugins-1.4.16]# chkconfig --add nagios
[root@Nagios nagios-plugins-1.4.16]# chkconfig --level 35 nagios on
[root@Nagios nagios-plugins-1.4.16]# chkconfig --add httpd
[root@Nagios nagios-plugins-1.4.16]# chkconfig --level 35 httpd on
